While driving for a couple of hours at high speed, I turned off the highway and slowed to a stop a t a set of lights and when I accelerated in 1st with the pedal half way to the floor up to 5k rpm, the car started to "judder" {shake a little} then into 2nd the same thing. It was up a slight to moderate incline and as I gave it some gas, the car barely sped up at all. So I limped about 1k home and parked the car. It felt as if the clutch was going. The car would not accelerate even though I was giving it enough gas. {So yes, I ordered a clutch, before I knew what the problem was.} Anyway, 2 spark plug wires came off and my mechanic told me that the vibration caused them to come off. The wires only have a 2,500 kms on them and yes most of that was high speed + high revs = more vibration.

Does this seem like a plausable situation?

Neil,
I have had a problem with my #2 plug wire coming off if I drive the car hard enough. I have gotten into the habbit of checking them a couple of times a month. I don't think you can crip the boots to get a better seal.

Thanks. I guess I may have to look under my hood more than once every 3 years.

Did the engine rev up and the car not accelerate or did the engine not rev up either?

Check your sparkplug for leakage between the metal and insulator. I've had this happen twice. In each case the insulator was loose enough to blow the boot off but not the insulator.

Yes the engine increased in noise and the revs went up like they should if I was in neutral [then it would grab and then let go etc....} It was a jerky ride.

I have had this (spark plug wire came loose) in the past. But probably pushing the insulation boot very tightly helped, so for a couple of years for now, hasn't happened.

I never had it happen, but imagining a scenario where it could... All the 924-specific plug wires I've used, whether OE or aftermarket were/are meant to go onto plugs that've had the tip unscrewed, so the little threaded stud is exposed. If this type of connector were used with plugs with their tips still on, they might go on and place the tip close enough to the connector contact to actually work, but they'd be way more likely to slip off. Mine are actually real tough to pull off - have to use plug wire pliers (or needle nose for the metal connectors) every time.

my wires have a tendency for breaking when I try and take them off the sparkplugs .... There is no way that they will come loose on their own.
